ИСПОЛЬЗОВАНИЕ ПАКЕТА «MAPLE» ДЛЯ ВЫБОРА НАИБОЛЕЕ ОПТИМАЛЬНЫХ ТРАСС ПЕРЕДАЧИ ЭЛЕКТРИЧЕСКОЙ ЭНЕРГИИ В СИСТЕМАХ СЕЛЬСКОГО ЭЛЕКТРОСНАБЖЕНИЯ

ИСПОЛЬЗОВАНИЕ ПАКЕТА «MAPLE» ДЛЯ ВЫБОРА НАИБОЛЕЕ ОПТИМАЛЬНЫХ ТРАСС ПЕРЕДАЧИ ЭЛЕКТРИЧЕСКОЙ ЭНЕРГИИ В СИСТЕМАХ СЕЛЬСКОГО ЭЛЕКТРОСНАБЖЕНИЯ

Abstract

The authors calculate technical and economic performances of the rural power networks in the Kachug region. To construct an optimal graph a specialized library of networks of the analytical package Maple is used as a tool. For the presented electrical supply network, the authors make a program for graph constructing, where the circuit nodes correspond to the graph nodes, while the arcs are assigned of the weight equal to the total unit costs. The skeleton of the minimum weight that is the power line with minimum cost is found. The points inappropriate as regards communication costs are discarded. The problem of choosing the most efficient routing of electrical networks is solved.

Произведен расчет технико-экономических показателей сетей сельского электроснабжения Качугского района. Для построения оптимального графа в качестве инструмента использована специализированная библиотека networks аналитического пакета Maple. Для представленной сети электроснабжения составлена программа построения графа, для которого узлы схемы будут соответствовать вершинам графа, а дугам присвоен вес, равный суммарным удельным затратам. Найден остов минимального веса, то есть той линии электропередачи, которая имеет минимальные затраты. Отброшены нецелесообразные с точки зрения затрат связи. Решена задача выбора наиболее рациональной трассировки электрической сети.
